FLYTRAP.

Application filed February 1e, 1322. Serial no. 536,969.

To all whom itmay concern:

Be it known that I, FRED DAY, a citizen of the United States, residing at master, in the county of Union State of onth Dakota, have invented certain newand useful Improvements in F lytraps, or which the following is a specification;

lhis invention relates to traps especially adapted for use in connection with flies.

An important object of this invention is to provide a fly tr ap having novel meanswhereby the flies are caused to pass through a plurality of trapping domes and prevented from escaping so that the flies are caused to die from lack of n'ourislnnent. Further the invention aims to provide a fly trap embodying a novel form of dome which may be conveniently detached When it is desired to remove the dead flies.

Also the invention aims to provide. a fly trap of the classdescribed which is of highly simplified constructionpdurable use and cheap to manufacture. a i i Y Other objects and advantages of the invention will he apparent djiring v the course of the following description 4 i In he 'c qn' pa y ne r n f rm a part vof this application and in which like wnnmerals are employed "to designate like parts throughout the same,

Figure 1 is a vertical sectional view th th impr ed ep- Figure 2 is a detail sectional View illustrating the means for connecting the'various sections of the trap.

Figure 3 is a perspective of a supporting arm embodied in the invention.

Figure 4 is a fragmentary plan view of the rim of the dome, parts being shown in section to illustrate the means for connecti g he r t ei at d bo f h d m the rim.

In the drawing wherein forthe purpose flila -marssh w rp f e .smbad ment of theinvention the numeral 5 genera ly desi nate a Po s on on i g b 'lb'a conta n n PM ha n t e h m res ibn rec essed as indicatedat '6 to definefla conrtainer adapted .forthe rereption of the bait which is preferably a liquidstate -1he other edge portion of the pan 5 is extended downward-1y as indicated atl8 so that "the; re-

cessed portion 6 will be disposed above the level of thetableior other supporting sur-' 7 face. To provide a smooth edge, the outer to Figure Bit willbe seen that each sup-' porting arm 12 is' of U-shaped formation and consists of spaced parallel sides having their "terminal portions" bent upon themselves as indicated at l t-to provide attaching members adapted for insertion through apertures 15 in the inclined sides of the pan. As illustrated in Figure l the attaching fingers 14 flatly contact with the under sides "of the pan'while the spaced parallelcarms flatly contact with the top of the pan for holding ,the arms in position; i

The outer portions of the arms are extended upwardly andinwardly as indicated at 16 so as to act'as a" retaining means for the base 18 of a pair of trapping screens.

As'illustrated in Figure '2' the base 18is of channel-shaped formation and is provided With upper and lower sides between which the lower terminal portions of the trapping sections 19 and 20 are arranged. After'the trapping sections 19 and 20 are -thus arranged between the upper and lower sides of the base 18 as illustrated in Fig. 2 the lower side of the base is punched inwardly as indicated at 22 so as to provide a plurality of knobs which engage the reticulated edge portions' of the trapping sections 19 and '20 whereby to securely and positively connect M i As illustrated in Figurel the upper por tion of fi'he reticulated trapping section 20 is formed with plurality of radial incisions which define partly ,seve'red portions'fbe nt ;upwardly to provide tapering baffle elements Q vhich prevent flies "froni returning through the opening formed by extending the prongs upwardly. It willbe seen that as the flies crawl upwardly within the trapevented from escaping between the V of the pan.

ping section 20 they will pass through the opening in the top of the same and will be prevented to some extent in returning by way of the opening because of the upwardly extending portions 26.

The outer trapping section 19 is extended a substantial distance above the inner trapping section 20 and has its upper portion formed with a gradually tapered outlet 28 through which flies pass in seeking the light. Of course the flies are prevented from escaping by moving downwardly within the trapping section 19 as the lower portion of the trapping section 19 is securely connected to the section 20.

As the flies pass through the gradually reduced outlet 28 they enter a dome 30 which constitutes a iinal receiver for the flies. When the flies enter the dome 30 they are prevented from escaping and die as a result of lack of nourishment.

The lower portion of the reticulated dome 30 is provided with a rim 33 having inner and outer metallic sides which define a channel into which the lower portion of the reticulated body is extended. lVith particular reference to Figure 2 it will be observed that the inner side of the rim 33 is formed with indentations 35 which define outwardly extending projections to engage the lower portionof the reticulated dome and thereby securely connect the dome to the rim.

As illustrated in Figure 2 the ends of the rim are overlappedand are connected by the outwardly extending projections formed by the indentations 35. Also the outer side of the rim 33 is for-med 'with indentations to correspond to the indentations in the inner side of the rim and to receive portions of the body 30.

Also the base 18 is overlapped at its ends and the ends are connected by the projections formed bythe indentations 22.

In preparing the device for use suitable bait is placed within the recess portion 6 of the pan and the inner and outer trapping sections 19 and 20 are subsequently placed in position. The base 18 is flatly mounted on the arms 12 and is held in position by the inwardly extending portions of the upstanding sides of the arms. That is to say that portion 16 of each ar 11 yieldably holds the base 18 against upward movement.

The dome 30 is now placed in position by inserting the rim 33 within the annulus 4A formed by extending the upper side of the base 18 upwardly. The rim 33 is snugly received within the annulus 44 whereby to connect the dome to the base as illustrated in Figure 1. The device is now ready for use pass between the base and the raised portion The flies will now move upwardly through the openings in the top of the sections 19 and 20 and will enter the dome 30 where they are trapped. Should one of the flies crawl downwardly on the retic ulated trapping section 20 it will be confronted by the inwardly extending portion of the bottom of the base 18. As illustrated in Figure 2 the lower side of the base 18 is extended beyond the upper side of the base for a substantial distance so as to provide an annular battle which prevents the flies from passing out of the trapping sections. Upon reaching the inwardly extending annular battle which for the purpose or clearness is designated by the numeral 50 the flies will move inwardly and will be given another opportunity to pass through the opening in the top of the trapping section. WVhen the dome is filled or partially filled it may be detached and the contents of the same discharged. The device may be readily and conveniently cleaned as the several parts may be easily separated and owing to the construction illustrated the easy escape of flies is prevented. Y

Attention is'directed to Figure 1 wherein the rim portion of the pan is inclined downwardly to contact with the supporting surface so that the flies may crawl from the supporting surface into the trap by way of the incline. Also by inclining the edge portions of the pan gradually restricted entrance opening is provided.

Having thus described the invention what I claim is 1. A trap comprising a bait receiving pan, a plurality of radially extending arms car ried thereby, a base member of annular for mation mounted on said arms and having up per and lower sides arranged in spaced re lation, inner and outer trapping sections having their lower portions arranged between said upper and lower sides, the lower side of said base being provided with projections engaging the lower portions of said trapping sections, the lower side of said base being extended inwardly for a substantial distance beyond the upper side of the base, thereby to define an annular baiile.
